Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ceiling material fixing device for a ceiling-embedded air conditioner.

Conventional technology In the past, the main body of the air conditioner was embedded inside the ceiling.
And in a hanging device, installed on the ceiling surface,
The opening/closing panel of the decorative panel joined to the main body is constructed as shown in FIGS. 5 to 7. That is, the panel frame 30 of the opening/closing panel is formed in a rectangular shape, and holding pieces 32 are provided on all sides on the lower side, on which the same ceiling material 31 as the surrounding ceiling material is placed. A fixing piece 33 rising perpendicularly to the holding piece 32 is provided with elongated holes 34 at several appropriate locations. Next, when the ceiling material 31 is placed on the holding piece 32, the L-shaped holding plate 35 is positioned inside the fixing piece 33 from both sides, and the screws 37 are screwed into the screw holes 36 and 34 to fix it. That is, as shown in FIG. 6, the ceiling material 31 placed on the holding piece 32 is
It is held down from above with a holding plate 35 and fixed with truss-shaped screws 37. And the thickness A of the ceiling material 31
There are various types of ceiling material 31 with a thin thickness A' as shown in FIG. corresponding to the type of thickness A′,
It was for fixing the ceiling material 32.

Problems to be Solved by the Invention In such a conventional configuration, since the hole provided in the fixing piece 33 is an elongated hole 34, it cannot be made into a countersunk hole, and a truss-type screw 37 has no choice but to be used. As a result, the remaining portion of the elongated hole 34 is exposed, making the appearance even worse. Furthermore, if the thickness A and the thickness A' are different, the holding plates 35 on both sides must be changed in vertical and longitudinal direction, which poses the problem of complicating the work of fixing the ceiling material 31. It was hot.

This invention solves these problems,
To provide a ceiling material fixing device for a ceiling-embedded air conditioner that can be easily fixed even if the thickness of the ceiling material changes.

Means for Solving the Problem In order to solve this problem, the present invention includes a decorative panel joined to the main body, an opening/closing panel provided in the center of the decorative panel forming an inlet and an air outlet, This opening/closing panel has a fixed piece formed in a rectangular shape and provided vertically on the longitudinal side, and a panel frame provided with a holding piece that protrudes orthogonally to the fixed piece to hold the ceiling material. An L-shaped holding plate is fixed to the fixing piece, and a cut-and-raised piece formed to hold down the ceiling material from above is provided on one piece of the holding plate.

Effect With this configuration, after the ceiling material is placed on the holding piece, the holding plate is fixed to the fixed piece, and the cut and raised piece provided on the holding plate is held down so as to bite into the upper surface of the ceiling material, and the ceiling material is held down. It will be fixed.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In FIG. 4, 1 is a main body 1 of a ceiling-embedded air conditioner suspended in the attic, and inside this main body 1 is a partition plate 2 having an opening.
A blower 3, a heat exchanger 4, a chamber unit 5, and an air filter 6 are provided. The main body 1 is joined to a decorative panel 18 provided facing a ceiling surface 19. This makeup panel 1
Reference numeral 8 indicates a frame 7 forming the surrounding area and suction ports 17 on both sides.
and air outlets 16 similarly formed on both sides,
An opening/closing panel 8 provided in the center for inspection etc. is provided.

As shown in FIG. 1, this opening/closing panel 8 has a panel frame 9 formed into a box-like rectangular shape, and this panel frame 9 has fixing pieces 20 on both sides in the longitudinal direction and on both sides of the short side. A side plate 21 and a holding piece 22 which is perpendicular to the fixing piece 20 and on which the ceiling material 12 is placed are provided. The fixing piece 22 is provided with countersunk holes 14 at several appropriate locations, and the ceiling material 12 is attached to the holding piece 2.
2, an L-shaped holding plate 10 fixed by the countersink 14 is provided. The presser plate 10
consists of a fixing part 10a and a cutout part 10b, and is provided with a screw hole 23 that matches the countersunk hole 14, and a cut-and-raised piece 11 formed by notching a T-shape. By manually pressing the piece 11 from above, it can be easily bent downward.

FIG. 2 is a longitudinal sectional view of the same, in which the holding plate 10 consisting of the fixing part 10a and the cutout part 10b is fixed together with the countersink hole 14 of the fixing piece 20 by a countersunk screw 24,
Even if the thickness A of the ceiling material 12 changes from thick to thin, it is fixed by the cut and raised pieces 11.

In the above configuration, the ceiling material 12 is of the same type as the surrounding ceiling surface 19 in most cases, and the ceiling material 12 is mounted on the holding piece 22. Next, screw holes 23 in the fixing part 10a of the holding plate 10 and countersink holes 1 in the fixing piece 20.
4 and fix the presser plate 10 on both sides with countersunk screws 24. Then, the cut and raised piece 11 is pressed and fixed by hand or with something such as a screwdriver so that it bites into the upper surface of the ceiling material 12.

Effects of the Invention As is clear from the description of the above embodiments, the present invention includes a countersink in the fixed piece of the panel frame, a holding piece that holds the ceiling material perpendicularly to the fixed piece, a fixed part and a cutout part. A cut-and-raised piece is provided in the notch of the holding plate to fix the holding plate and the fixed piece, and the cut-and-raised piece is bent so as to bite into the upper surface of the ceiling material and pushed in. Since the ceiling material is fixed, there is no gap between the opening/closing panel and the suction port as in the conventional case, and the screw heads do not protrude, making it possible to create a cosmetic structure without any aesthetic problems. You can get the panel.
In addition, the method of fixing the holding plate means that it will be fixed in the same direction even if the thickness of the ceiling material changes, making it easier to fix the ceiling material as it requires on-site installation work.
This has the effect of eliminating complexity.
